Aim: Asprosin is a newly identified peptide hormone that is a proteolytic product of a protein called profibrillin. This study aims to examine the effects of eight weeks of moderate-intensity and high-intensity interval training on plasma levels of Asprosin, insulin resistance, and certain body composition indices in overweight and obese women.
Methods: This study was a quasi-experimental and applied research in which 45 subjects were purposefully selected and randomly divided into three experimental and control groups of 15 subjects each. The training program (high-intensity interval training and moderate-intensity interval training) consisted of four and 30 minutes of running, respectively, at 45-60% and 85-95% of maximum heart rate. The first training session was conducted at 45% and 85% of maximum heart rate, respectively, and the intensity of the training was gradually increased by 5% each week. After reaching 60% and 90% of maximum heart rate, respectively, this intensity was maintained until the end of the training program. Blood sampling was performed after 12 hours of fasting in two stages, pre- and post-test, and research variables were measured. To assess the normality of data distribution, the Shapiro-Wilk test was used, and for intra- and inter-group changes, the dependent t-test and covariance analysis were employed at a significance level of( p≤ 0.05).
Results The results showed that all the indicators examined in this study had a significant difference between the two training groups and the control group (p<0.05). Also, a significant difference was observed in the changes in asprosin concentration between the two high-intensity interval training and moderate-intensity continuous training groups (p<0.05). In the intra-group comparison, plasma asprosin levels, body weight, body mass index, fat percentage, and insulin resistance in both training groups in the post-test phase decreased significantly compared to before training (p<0.05).
Conclusion: Therefore, given the reduction in Asprosin, insulin resistance, and various body composition indicators, it is recommended that overweight and obese individuals engage in high-intensity interval training and moderate-intensity continuous training methods to prevent obesity-related diseases.
